1. A transparent display system, comprising:
a display panel, from which a background located behind the display panel is seen;
a data acquisition module, adapted to capture a field luminance of a field where the display panel is located and a display information luminance of display information of the display panel, wherein the field luminance comprises a foreground reflective light luminance and a background transmissive light luminance; and
a computation module, coupled to the display panel and the data acquisition module, the computation module determining whether a luminance contrast of the display information falls within a range from a lower boundary to an upper boundary based on the captured field luminance and the display information luminance, wherein the luminance contrast of the display information equals to the field luminance plus the display information luminance and then divided by the field luminance, if the luminance contrast of the display information is determined not falling within the range from the lower boundary to the upper boundary, a luminance contrast optimization procedure is performed; and if the luminance contrast of the display information is determined falling within the range from the lower boundary to the upper boundary, the display information being output.
